Difference between SystemVerilog 3.1a LRM by Accellera and IEEE Standard for SystemVerilog

In reply to vk7715:
The difference is the Accellera 3.1a version nearly 20 years old, has lots of mistakes, obsolete, and only contains the enhancements SystemVerilog made over the Verilog 1364-1995 standard. So do not use it.

Up until now, I always thought the LRM was 3.1a document by Accellera
